Relationship between news media coverage of medical research and academic medical centers and people volunteering for clinical trials

In academic medical centers an untested assumption is that positive media attention aids recruitment of patients into a medical study while negative news reporting is damaging. In this study we examine associations between the amount of newspaper coverage concerning medical research and the number of people who volunteer, and the positive or negative content of the reporting. We find evidence that a positive relationship, though not statistically significant, exists between the volume of media coverage and volunteerism; a positive relationship exists between positive media coverage and volunteerism; and no existence of an inverse relationship between negative news coverage and volunteerism. These results lay a foundation for more in-depth exploration into the role news media play in this type of volunteerism.     

The use of alternative work arrangements by the jobless: Evidence from the CAEAS/CPS

Alternative work arrangements (AWAs), such as contracting, consulting, and temporary work, have been criticized as providing only atypical, even precarious, employment. Yet they may also allow workers to locate suitable job matches. Exploiting data from four Contingent and Alternative Employment Arrangement Supplements to the Current Population Survey, we investigate the initial job-finding strategies pursued by the unemployed. Within the narrow window offered by the data, we find that unemployed workers who become reemployed are more likely to find work in AWAs than in regular, open-ended employment. When we evaluate the use of AWAs against unemployment, there is also evidence that the jobless are entering AWAs as pathways out of their initial labor market state.     

Inference for clusters of extreme values

Summary. Inference for clusters of extreme values of a time series typically requires the identification of independent clusters of exceedances over a high threshold. The choice of declustering scheme often has a significant effect on estimates of cluster characteristics. We propose an automatic declustering scheme that is justified by an asymptotic result for the times between threshold exceedances. The scheme relies on the extremal index, which we show may be estimated before declustering, and supports a bootstrap procedure for assessing the variability of estimates.     

Rescuing from oblivion: social characteristics and career destinations of early British ‘sociology’ graduates, 1907–39

Those students who were among the first sociology graduates in the UK barely feature in standard histories of the discipline, which all have an intellectual and institutional focus. This article remedies this neglect by researching the social backgrounds and later careers of sociology graduates from the London School of Economics and Political Science [LSE] and Bedford College for Women from the first such graduate in 1907 until those graduating in the 1930s. Data for this exercise were compiled from a variety of sources. The more important are: UK censuses, especially that of 1911; various civil registration records; archived student files; and, for the graduates who entered university teaching, issues of the Yearbook of the Universities of the Empire [later the Commonwealth Universities' Yearbook]. The dataset includes all identified graduates in the BSc(Econ), Special Subject Sociology, degree from 1907 to 1935 and all in the BA (Honours) in Sociology degree from 1925 to 1939. LSE sociology graduates tended to be older and to have more cosmopolitan backgrounds, with fathers more likely than for Bedford College graduates to come from commercial rather than professional backgrounds. Both institutions' graduates' careers tended to the Civil Service and local government. LSE graduates gravitated to education, especially to higher education if male, whilst those of Bedford College went into welfare work, countering a stereotype from some previous literature that especially women graduates were heavily constrained to follow careers in schoolteaching. The article also gives comparisons with the social‐class profile and career destinations of several cohorts of postwar sociology graduates, noting a number of similarities.     

Small Area Estimation via Multivariate Fay–Herriot Models with Latent Spatial Dependence

The Fay–Herriot model is a standard model for direct survey estimators in which the true quantity of interest, the superpopulation mean, is latent and its estimation is improved through the use of auxiliary covariates. In the context of small area estimation, these estimates can be further improved by borrowing strength across spatial regions or by considering multiple outcomes simultaneously. We provide here two formulations to perform small area estimation with Fay–Herriot models that include both multivariate outcomes and latent spatial dependence. We consider two model formulations. In one of these formulations the outcome‐by‐space dependence structure is separable. The other accounts for the cross dependence through the use of a generalized multivariate conditional autoregressive (GMCAR) structure. The GMCAR model is shown, in a state‐level example, to produce smaller mean square prediction errors, relative to equivalent census variables, than the separable model and the state‐of‐the‐art multivariate model with unstructured dependence between outcomes and no spatial dependence. In addition, both the GMCAR and the separable models give smaller mean squared prediction error than the state‐of‐the‐art model when conducting small area estimation on county level data from the American Community Survey.     

The ‘Mosquito’ and the transformation of British public space

This paper explores the implications of the ‘Mosquito’ Ultrasonic Teenage Youth Deterrent device. It is used in Britain to exclude young people from public spaces despite contravening British law and European and International Human Rights legislation. The paper argues that the device is changing the relationship young people have with public spaces around them. Additionally, the paper discusses how the device has transformed the ways in which specific public space legislation is implemented and enforced to the extent that it can be viewed as a purchasable manifestation of the powers conferred upon police officers through legislative acts. The existing academic literature regarding the Mosquito is to be discussed and utilised. The device is examined against the Anti-Social Behaviour Act 2003 and the Equality Act 2010. The paper argues that the device itself can be labelled as anti-social and contravenes several pieces of UK legislation with regard to anti-social behaviour and discrimination. Finally, the paper critically appraises the impact of combatting youth anti-social behaviour with a device which itself can be labelled as anti-social.     

Classed,raced, and gendered biographies: young people's understandings of social structures in a boomtown

As young people attempt to adapt to a rapidly changing society, how they experience school and work has undergone significant changes in recent decades. Youth researchers attempting to understand these changes have drawn heavily on the concepts of agency and structure. In the process, researchers often end up taking a ‘middle-ground’ approach and in turn have critiqued the theorizing of Ulrich Beck for being too focused on agency. This article engages with this debate by examining young people's understandings of the social structures shaping their lives within the constantly changing environment of a boomtown. Drawing on qualitative in-depth interviews with high school students, post-secondary students, and young workers, it was found that most young people were able to recognize how class had shaped their lives, only Aboriginal young people discussed how race/ethnicity had shaped their lives, and only young women understood how gender had shaped their lives. The findings suggest that the specific local context that young people experience their school and work lives within is important in their reflexive understandings of their biographies. In this case, the boomtown environment helped to highlight difference and make only certain social structures visible to particular young people.     

Fractional Price Matching Policies Arising from the Ocean Freight Service Industry

We consider a situation in which shippers (customers) can purchase ocean freight services either directly from a carrier (service provider)in advance or from the spot market just before the departure of an ocean liner. The price is known in the former case, while the spot price is uncertain ex‐ante in the latter case. Consequently, some shippers are reluctant to book directly from the carrier in advance unless the carrier is willing to “partially match” the realized spot price when it is lower than the regular price. This study is an initial attempt to examine if the carrier should bear some of the “price risk” by offering a “fractional” price matching contract that can be described as follows. The shipper pays the regular freight price in advance; however, the shipper will get a refund if the realized spot price is below the regular price, where the refund is a “fraction” of the difference between the regular price and the realized spot price. By modeling the dynamics between the carrier and the shippers as a sequential game, we show that the carrier can use the fractional price matching contract to generate a higher demand from the shippers compared to no price matching contract by increasing the “fraction” in equilibrium. However, as the carrier increases the “fraction,” the carrier should increase the regular price to compensate for bearing additional risk. By selecting the fractional price matching contract optimally, we show that the carrier can afford to offer this price matching mechanism without incurring revenue loss: the optimal fractional price matching contract is “revenue neutral.”
